To determine the range in the number of pools sold over the six-month period, we need to follow these steps:
1. List the number of pools sold:
- February: 11 pools
- March: 10 pools
- April: 12 pools
- May: 16 pools
- June: 15 pools
- July: 18 pools
2. Identify the highest number of pools sold:
- The highest number is 18 pools (sold in July).
3. Identify the lowest number of pools sold:
- The lowest number is 10 pools (sold in March).
4. Calculate the range:
- The range is the difference between the highest and the lowest numbers.
- Subtract the lowest number of pools sold from the highest number of pools sold: [tex]\( 18 - 10 = 8 \)[/tex].
Therefore, the range in the number of pools sold during this period is [tex]\( 8 \)[/tex] pools.
